My predecessor, Kobie du Preez, did an amazing job enhancing the quality of the publication, inspiring me to try new techniques and to enhance it even further with every opportunity. Unfortunately the cost of producing a small run for the Society has made it too expensive to print The Strandloper in hard copy and a descision was taken to follow the international trend of producing an electronic publication, that will hopefully reach more people. By using this format we are no longer bound by printing restraints and the high costs of producing the publication. This should see the Society’s newsletter be issued more regularly. Even so, this will be a learning curve, and I am hoping that whoever follows as editor, will also strive to improve on what we have done so far. Aricles are the lifeblood of a publication like The Strandloper. I am greatly indebted to all the authors that contributed and would like to encourage all members to try their hands at writing small articles. This is their newsletter and the most fun I have had was to enhance and publish articles by our general readers. “The more that you read, the more things you will know.

BMC Ecol Evo (2021) 21:35 BMC Ecology and Evolution https://doi.org/10.1186/s12862-021-01754-4 RESEARCH ARTICLE Open Access Trophic specialisation refected by radular tooth material properties in an “ancient” Lake Tanganyikan gastropod species fock Wencke Krings1,2* , Marco T. Neiber1, Alexander Kovalev2, Stanislav N. Gorb2 and Matthias Glaubrecht1 Abstract Background: Lake Tanganyika belongs to the East African Great Lakes and is well known for harbouring a high pro- portion of endemic and morphologically distinct genera, in cichlids but also in paludomid gastropods. With about 50 species these snails form a fock of high interest because of its diversity, the question of its origin and the evolutionary processes that might have resulted in its elevated amount of taxa. While earlier debates centred on these paludomids to be a result of an intralacustrine adaptive radiation, there are strong indications for the existence of several lineages before the lake formation. To evaluate hypotheses on the evolution and radiation the detection of actual adaptations is however crucial. Since the Tanganyikan gastropods show distinct radular tooth morphologies hypotheses about potential trophic specializations are at hand. Results: Here, based on a phylogenetic tree of the paludomid species from Lake Tanganyika and adjacent river systems, the mechanical properties of their teeth were evaluated by nanoindentation, a method measuring the hard- ness and elasticity of a structure, and related with the gastropods’ specifc feeding substrate (soft, solid, mixed). Results identify mechanical adaptations in the tooth cusps to the substrate and, with reference to the tooth morphology, assign distinct functions (scratching or gathering) to tooth types.

  • Scales of Endemism: Challenges for Conservation and Incentives for Evolutionary Studies in a Gastropod Species Flock from Lake Tanganyika
    michelQX 23/10/03 11:50 am Page 1 JOURNAL OF CONCHOLOGY (2003), SPECIALPUBLICATION 3 1 SCALES OF ENDEMISM: CHALLENGES FOR CONSERVATION AND INCENTIVES FOR EVOLUTIONARY STUDIES IN A GASTROPOD SPECIES FLOCK FROM LAKE TANGANYIKA. ELLINOR MICHEL1, JONATHAN A. TODD2, DANIEL F.R. CLEARY1, IRENE KINGMA1, ANDREW S. COHEN3 & MARTIN J. GENNER1 Abstract The Lake Tanganyika benthos presents a highly biodiverse system on many spatial scales. We present here an analysis of regional ( ) diversity and local ( ) diversity of the Lavigeria species flock, the most common and speciose of the endemic gastropods, across the currently accessible sections of lakeshore. We found significant differences in Lavigeria gastropod diversity among regions within the lake, and that regional species richness was strongly associated with the presence of local, short-range endemics. Species richness at individual sites was not correlated with total species richness of the surrounding region. Although sites frequently encompassed high sympatry of congeneric species, highly disjunct species distri - butions lead to non-predictable community assemblages. Keywords distributions, ‘thiarid’, regional sampling, endemicity, Lavigeria, alpha and gamma diver - sity INTRODUCTION Lake Tanganyika is renowned for spectacular radiations of endemic molluscs, crus- taceans and fish. Within the malacofauna of this ancient rift lake, the ‘thiarid’ gastropods are by far the most species-rich and show exceptional morphological diversity and convergence with marine forms. At depth the lake is permanently anoxic (Coulter 1991), and due to the steep rifting margins benthic macro-organisms are restricted to a narrow rim commonly less than one kilometre wide. Despite this narrow distribution, the biogeography of Tanganyika’s endemic species remains poorly known, making it diffi- cult to inform conservation decisions.

In his formal plan for the institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian FoUdife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world o^ science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.

  • The Demonstration of Speciation in Fossil Molluscs and Living Fishes
    Biological Journal of the Linnean Society (1985), 26: 325-336. With 3 figures The demonstration of speciation in fossil molluscs and living fishes G. FR Y E R , Freshwater Biological Association, Windermere Laboratory, The Ferry House, Ambleside, Cumbria P. H. GREENWOOD AND J. F. PEAKE British Museum ( Natural History), Cromwell Road, London Accepted for publication July 1985 Contrary to a recent assertion, freshwater (and marine) prosobranch gastropods and freshwater bivalves are subject to considerable variability. This, and the lack of a detailed understanding of the taxonomy of the forms involved, makes it difficult to accept that the changes documented by Williamson (1981) in a fossil sequence from Lake Turkana (Africa) represent speciation events. That 10 lineages, involving gastropods and bivalves, should change simultaneously, and the deviant forms should then simultaneously become extinct, can, we believe, be more plausibly attributed to ecophenotypic responses to environmental changes than to speciation. In revealing the pattern and process of evolution, both fossil and living forms are helpful, but in demonstrating the fine-scale events during and after speciation in living animals one can utilize techniques and observations that cannot be applied to fossil material. African cichlid fishes are particularly informative in this respect. Their current explosive radiation can be interpreted as a punctuational event in evolution.

The shell of Vinundu has equal axial and spiral macrosculpture, producing characteristic regular nodes at the sculptural intersections. Reproduction in Vinundu is oviparous, in contrast to the ovoviviparous habit of its sister group, Lavigeria. Radular teeth and isotope values indi- cate that this is a grazer. Vinundu species are readily distinguished from their sister clade Lavigeria by conchological, anatomical and molecular characters. The two Vinundu species are common in deep water, rocky habitats of this clear-water, ancient lake.

A, representing another ovoviviparous lake clade that has acquired a uterine brood pouch independently. Within the phylogenetic framework provided by recent molecular analyses, the distant relation of these two taxa is corroborated by many external and internal anatomical differences. Comparison of the brood pouches demonstrates that they each bear unique features consistent with their independent modification for brooding. Despite representing functionally analogous structures, they also share several similarities in organization likely representing symplesiomorphies of the Lake Tanganyika species flock. The ontogeny is characterized by the presence of a velum and by delayed calcification producing a characteristically wrinkled embryonic cap. Comparison with other brooding cerithioideans reveals that T. horei and Lavigeria sp. A retain many more embryos than other freshwater cerithioideans of comparable size with a uterine brood pouch, possibly facilitated by the presence of longitudinal lamellae.
